Summary of current data holdings

71 million criminal justice events and counting

The figure below illustrates annual counts in the current CJARS database of five major events in criminal justice case processing: arrest or booking, charges filed, and the beginning of terms of probation, prison, and parole.

CJARS Data Collections to Date

At this time, the CJARS database includes records on over 3 million criminal justice events per year in recently available data. These come from a variety of sources, with court records representing the bulk of the measured events. The figure above provides just an overview of events though, not an exhaustive list. We also gather, for example, information on case dispositions, sentencing, and program participation. A current primary goal is to improve procedural coverage to track the full lifecycle of criminal episodes.
